BATTERY.

To all whom it may concern Be it known that I, ROBERT C. WOOD, a citizen of the United States of America, residing at the city of New York, in the county and State of New York, have invented certain new and useful Improvements in Batteries, of which the following is a specification.

My invention relates to primary batteries and it consists as one feature in the manner in which I assemble the parts constituting the negative element; also in the manner in which I make up the combination of the negative and positive elements.

Figure 1, is a perspective View of one part of a device embodyin my invention. Fig. 2, is a similar View 0 a second part of said device. Fig. 3 is .a similar view of the combined elements. Fig. L is a central Vertical sectional view of the device of Fig. 1. Fig. 5 is a perspective view of a slightly modified form of one part of the structure. Fig. 6 is a perspective view of the oxid adapted for use with other parts like those of Fig.

1 My purpose is to form a combined charge for a battery consisting of a positive and a negative element, so assembled that they may be readily and conveniently assembled at the factory, shipped as assembled, remain in perfect adjustment where shipped and until and when used, adapted to be secured in place in a jar with a'minimum of labor and without the necessity for readjustment of the parts, also to be as readily removed there from without the necessity of gloves or other protection for the hands, because there will be no necessity for touching the parts which have been submerged, and yet may be as readily disassembled, if that be desired, and, as a subsidiary feature, to accomplish this in such a way as to permit a central suspenr SiLii. and connection and thereby secure the important results in the way of heavy current and long life to the battery which such suspension and connection insures.

In constructing my device, I first stamp out or otherwise provide a structure 1, like a part of a box with a series of openings 2, preferably four, the edges of said openings being shaped to form sockets as at 3. This structure has a central boss 4 of sullicient size to give it strength to withstand considerable pressure and through this central boss there is an aperture or opening 5. The complemental partof the structure is in one form, a duplicate of part 1.

[in one side I sometimes provide extensions 7, adapted to it in slots 8, in the other side and thus constitute a variety of hinge or ca; I then mold blocks of oxid of copper 9, s. a size and form adapted to set with in and lit into spaces left between the socket portions 3 of one member of the box and those of the other member. Having seated the requisite number of said blocks 9, in the sockets of one member, I place the other member over it, then insert a bushingof insulating material 10 into the holes or apertures 5. Over this bushing I pass two sleeve like cylinders of insulating material 11 which are respitively longer than the projecting parts oi bushing 10. Then I'pass a bolt 12 through said bushing, set the zines 13-upon the shaft the belt 12, first applying washers l4 and a terminal 15, and turn down the bolt 16 until they are all tightly secured together. Then the oXid blocks will be held firmly in place, the box like parts bearing tightly upon them and furnishing a more perfect electrical contact than could otherwise be secured, since considerable pressure may be used in bringing the parts together, which, as the socket flanges bear upon a surface of the oXid blocks, may besustained without fracturing said blocks, a liability always present in the majority of structures: wherein oxid blocks are used, unless the sessure is too slight to create that perfect cor "act which is necessary to produce a satisfactory battery.

At the upper side, or on one side of the boX like pieces, I preferably project tan; like extensions 17, 18, which may be struck up from the material of the box pieces. These tangs I pierce to accommodate a bolt 19 and bend over, so that they preferably lap one over the other, with the apertures in registry. Then I slip a nut 20 under one (this is done before bringing parts 17 and 18 together). Having brought the parts together, I pass a bolt 19 (preferably provided with an extra nut 21) down through the apertures in the tunes 17 and 18, and the device is ready to be placed in a j ar in which it;

may be readily suspended by the single bolt 19, held to the cover, 23, by a wing or other nut 22, which furnishes a ready means of connecting one of the circuit wires, the other being secured to the terminal extending from bolt 12, as shown at 15. j

Instead of the box of Figs. 1, 2, I sometimes employ one like Fig. 5, which is quite sign of the parts,

similar to the first one, but designed to ac connnodate a single block of oxid Q/l, pierced with an aperture to permit the entrance therein of the bosses 26.

One part of this box may be made a little larger, (as a box cover would be), to fit over the other part, and when I propose to use a single block of oXid in constructing the negative element, I prefer to omit the projections which form the sockets 3.

The arrangement of the insulators permits the transmission of pressure by the larger sleeves and yet insures that no portion of the bolt 12, adjacent to the negative element, shall be unprotected.

The arrangement of a central suspension of the zincs is especially advantageous, since it insures an evenness of action which is very dil'licult to attain, but which in this device is particularly well secured, and the depermits the establishment iot a particularly intimate contact, with all ft-he beneficial results attendant thereon, and the easy maintenance '25- of such condition. Then too, as initially stated, though the charge, that is the first part of it composed of the negative and positive elements, may be shipped already assembled, they may equally well be shipped otherwise, thus saving freight, and readily and correctly assembled by unskilled labor. Again though the combination may be detached from. the jar cover by removing one bolt, nevertheless, it there be a desire to disassemble, the removal of bolt 19 from the nut 20 andnut 16 from bolt 12, permits the separation of the charge into its integral parts with the minimum of labor. v
